When working with ERPNext, there may be times when you need to reset the MariaDB server's root password. This can be a delicate task, especially if you aren’t familiar with database management. Here’s a step-by-step guide to resetting the MariaDB password, with a few troubleshooting tips to help you along the way.

Note: This process might affect your existing database. Please back up your database before starting.


Step 1: Stop the MariaDB Server

The first step is to stop the MariaDB server. Use the following command:

sudo service mysql stop

Step 2: Switch to Root User Access

Some commands may require root access. If you’re not already a root user, use:

sudo su

Step 3: Restart MySQL in Safe Mode

In safe mode, MariaDB starts without loading the user privilege tables, allowing you to reset the password.

mysqld_safe --skip-grant-tables &

After running this command, enter the MySQL shell as the root user:

mysql -u root

Step 4: Access the MySQL Database

Once inside the MySQL shell, switch to the MySQL system database by running:

use mysql;

Step 5: Update the Root Password

Depending on your MariaDB version and setup, use one of the following commands to reset the root password:

Option 1:

UPDATE user SET authentication_string = password("root") WHERE User='root';

Option 2:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');

If neither command works, you may need to check the my.conf configuration file in the MariaDB folder and adjust the permissions accordingly.

Step 6: Flush Privileges

To apply changes, run:

FLUSH PRIVILEGES;

Step 7: Verify the Password Reset

After running the above commands, exit the MySQL shell and try logging in with the new password. Note that even if no success message appears, the password may still have been updated, so give it a try.


Troubleshooting Common Issues

While resetting the password, you might encounter errors. Here are some general troubleshooting tips:

  1. Error in Updating Password: If you receive an error during the password update, double-check your MariaDB configuration file (my.conf) and ensure that the commands used are compatible with your setup.

  2. Safe Mode Errors: Sometimes, mysqld_safe may fail to start if there are configuration issues. Review the error message provided and address any permission or configuration problems in the MariaDB setup.

  3. FLUSH PRIVILEGES Error: If this command fails, restart the MySQL server and try running the commands again.

Remember that every system setup can be different, so these are general guidelines. Adjust according to your environment if necessary.


By following these steps, you should be able to reset the root password on your MariaDB server, even while working with ERPNext.
